As for not attending the reunion taping, Maloof, who recently divorced Paul Nassif, "knows she's going to be asked about her children and the surrogacy," our source explains. "She is also not allowed to talk about her divorce; there is a gag order in place, and she was concerned she is going to be pushed into a corner and repeatedly asked about it, and that will compromise the divorce agreement.

"It is too dangerous and the repercussions too severe for her to put herself in that situation," our source close to Maloof adds.

Maloof was also concerned about attending the taping because of cast member Brandi Glanville. "In her Bravo contract, she has said she never wants her children to be a part of the show. Since Brandi brought up the surrogacy, that has exposed her children to exactly what she was trying to shield them from," our source says. "She does not trust that that subject will also not be touched on at reunion."

This isn't the first time Grammer has exited the hugely popular Bravo reality series: She quit the series prior to season three, telling us, "I didn't want to expose my personal life so much anymore. I had done that and was over that." Grammer ended up returning to the series.
